Throttle cleaning, huh? I've heard of that. Is it something I can do myself, or am I better off taking it to a professional? What exactly does a 'throttle body' even do?

Cleaning it yourself is possible, but you need to be careful. Plenty of videos online show the process. However, if you are not mechanically inclined, you could damage the throttle body. I recommend going to a workshop. They will diagnose it properly. It sounds like you have a defective throttle valve. In my case the car throttle was the problem and the whole engine throttle went crazy.

Thanks for the insight. Took it to a workshop and indeed the accelerator pedal module was defective, as suspected. Repair including parts and labor came to 205€. Now it's running smoothly again.

Higher fuel consumption and poor starts sound familiar. I had similar symptoms in my Mini Cooper. Have you checked the throttle body for carbon buildup? A simple throttle cleaning might solve the problem. Is the engine light on?
